ChangeLog

VersionDescription
Before 5.1.0 If called without parameter outside object, this function would have returned NULL with a warning.
Since 5.0.0 The object parameter is optional if called from the object's method.
Since 4.0.5 If object is a string, returns the name of the parent class of the class with that name.

Examples

Example 381. Using get_parent_class()

<?php

class dad {
   function
dad()
   {
   
// implements some logic
   
}
}

class
child extends dad {
   function
child()
   {
       echo
"I'm " , get_parent_class($this) , "'s son\n";
   }
}

class
child2 extends dad {
   function
child2()
   {
       echo
"I'm " , get_parent_class('child2') , "'s son too\n";
   }
}

$foo = new child();
$bar = new child2();

?>

The above example will output:

I'm dad's son
I'm dad's son too
